From what Iíve observed, machismo is triggered by fear. The fear of
appearing inadequate or unmanly is the basis of this exaggerated
preoccupation to prove virility and is the opposite of love (1 John
4:18).*

So, those who commit cruel acts against humans and other animals in a
vain attempt to prove their courage and manliness are actually cowardly
wimps who are over-compensating for their feelings of inferiority.

* 1 John 4:18
18 There is no fear in love; but perfect love casts out fear, because
fear involves punishment, and the one who fears is not perfected in
love.

"Joyful Curmudgeon"
An oxymoron?
No! I see all the beauty of God's creation and I'm joyful. At the
same time, I see all the suffering and corruption going on in the
world, and feel called to help expose and end it so that we may have true
peace and compassion.
